It looks great! I love the multiple options for a threat, and the many tables to roll on.
I would say that I think some of the paragraphs could use a little more white space, but that might just be a personal preference.
I want to run it with the undead version, so if I do I'll let you know how it goes!
I ran it the other day, so here's some feedback from running it.
- I ran the undead version using Mothership, it worked well and we all had fun.
- I didn't have the time to do much prep, but there wasn't anything needed further than the conversion and statting things up for Mothership. It has all the details needed to pretty much just pick up and run.
- The players managed to figure out pretty quickly what was the threat and why it was happening, and suited up in the space suits to avoid exposure. They also managed to successfully eject most of the undead out of the window in the medbay, leaving just one for them to attempt to fight and then run away from.
- The players rolled less than suggested due to how Mothership, but they gained a decent amount of stress regardless.
- Everyone was nice and easy to stat out from their descriptions.
- The pacing was very good in play, it was very satisfying that the final room had the enemies in it.
- The way the document was laid out was also nice and easy to read while playing, it's very nice.
- Personally I would have liked the room descriptions to be even shorter and bullet pointed the important parts, but I think that's just my style of GMing.
- The layout of the ship was also pretty good, it was a little hard to figure out from the way it was written. I did manage to draw it up after rereading it, as I was using a vtt, and like having a simple map
- Personally I would have found it useful to have a list of the crew with names and pronouns to reference when the players asked - I had to figure it out from the names mentioned throughout.
Overall, we had a lot of fun.
